Problems solved by technology

[0004] Using calcium sulfonate with high base value as raw material to produce lubricating grease, because of its excellent high and low temperature performance, mechanical stability, colloidal stability, oxidation stability, water resistance, corrosion resistance and anti-rust and anti-wear properties, it has been put into the market since then. Since then, it has attracted widespread attention in the grease industry at home and abroad. However, although the high-base value calcium sulfonate-based grease has excellent comprehensive properties, the high price of high-base value calcium sulfonate raw materials and its own complicated preparation At the same time, as people's requirements for environmental protection are getting higher and higher, the pollution of the environment by the sulfonation process that must be passed through the production process of high-alkaline calcium sulfonate is also increasingly concerned by people.

Description

technical field [0001] The invention relates to lubricating grease, in particular to a composite calcium sulfonate-calcium naphthenate zirconium-based octapolyurea lubricating grease and a preparation method thereof. Background technique [0002] Calcium sulfonate has been used as a detergent and antirust agent for lubricating oil for decades, and is widely used as an additive for internal combustion engine lubricating oil. Its technical development is mainly to make it highly alkaline, that is, to use calcium carbonate with a Active calcium alkylbenzene sulfonate or calcium alkyl carboxylate is dispersed in diluent oil to form a colloidal dispersion system. High base value calcium sulfonate can be divided into petroleum calcium sulfonate and synthetic calcium sulfonate according to different production methods. Calcium petroleum sulfonate is made with oleum or SO 3 Petroleum sulfonic acid, a by-product of the production of white oil from sulfonated mineral lubricating oil...
